AC Power Supplies, Connectors, and Cords for Catalyst
Switches
In this section you see the summary of AC power supplies, power connectors, and cords for Catalyst
6500/6000, 5500/5000 and 4500/4000 series, and Catalyst 3750, 2950, 2940, and 2900/3500XL series
switches. Refer to the Power Installation Guidelines in the tables that correspond in the next section for
international power requirements, DC power requirements, and other technical specifications.
Different Modules require different amount of power. Inline Power modules supplies the power to the IP
phones. Cisco has inline power module to power the IP phones. You have to choose the correct power
supply in order to support the various line cards, modules and Supervisor Engines on the switch. Cisco
offers a tool called the
Cisco Power calculator which can be used in order to choose the correct power
supply for your switch. Launch the
Cisco Power calculator and fill out the Product family, Supervisor
Engine, Input voltage, line cards and the number of PoE devices. IP phones are the example for PoE
devices and most of the IP phones belong to IEEE 802.3af Device - Class 2 (7W). Then the power
calculator shows the results of different choices of Power Supplies. From that you can choose the required
power supply. The power supplies successfully operate at their greatest capacity if the input voltage is
between 200 and 240 volts AC.
